Abstract

Method for improving copy protection of CDs, whereby a digital protection signal is placed in multiple positions on the CD, i.e. within each track on the CD.

Description

Dia Musik produzierende Industrie beklagt Umsatzeinbussen durch Raubkopien von Musik-CDs. The music-producing industry complains of a drop in sales through pirated music CDs.

Die Original-CDs werden durch einen digitalen Code vor unberechtigter Vervielfältigung geschützt. Dieser Kopierschutz kann jedoch mittels einfachster Aufnahmetechnik unterlaufen werden und ist damit wirkungslos. The original CDs are preceded by a digital code protected against unauthorized reproduction. This copy protection can, however, bypass using the simplest recording technique become and is ineffective.

Fakt ist, dass bei Erscheinen z. B. einer neuen "XXX-CD" jede verkaufte CD mehrfach kopiert wird. Dies ist auf den bisher angewendeten und völlig unzureichenden Kopierschutz zurückzuführen. The fact is that when it appears z. B. a new "XXX CD" every sold CD is copied several times. This is due to the Previously used and completely inadequate copy protection due.

Der Kopierschutz als solcher kann nicht verändert werden. CD-Aufnahmegeräte und Computer sind auf ihn programmiert. The copy protection as such cannot be changed. CD recorders and computers are programmed on it.

Ändern kam die Musikindustrie jedoch die Methode, mit der sie ihre Produkte schützt. However, the music industry came to change the method by which it protects its products.

Das neue, bisher nirgendwo praktizierte Verfahren besteht darin, dass die digitale Markierung für den Kopierschutz nicht, wie bisher, an den Beginn der CD gestellt wird. The new process, which has not been used anywhere before, exists in that the digital mark for copy protection not, as before, at the beginning of the CD.

Statt dessen wird das Kopierschutz-Signal idealerweise innerhalb eines jeden einzelnen Musiktitels placiert. Diese Methode unterbricht den Kopiervorgang zuverlässig, verhindert auch das Kopieren einzelner Titel und macht die neu aufzunehmende CD unbrauchbar. Instead, the copy protection signal is ideal placed within each individual song. This Method reliably interrupts the copying process, also prevents copying of individual titles and makes them new CD to be recorded unusable.
